Ectomycorrhizal association of Astraeus aff. hygrometricus (Pers.) Morgan with an oak forest relict in the Altiplano Potosino, Mexico

Introduction: In the high mountain ranges of the Altiplano Potosino there are relict forests of Quercus spp. The species of ectomycorrhizal fungi associated with these ecosystems are so far unknown.Objective: To know the morphology of Astraeus aff. hygrometricus (Pers.) Morgan associated with Quercu...

description Introduction: In the high mountain ranges of the Altiplano Potosino there are relict forests of Quercus spp. The species of ectomycorrhizal fungi associated with these ecosystems are so far unknown.Objective: To know the morphology of Astraeus aff. hygrometricus (Pers.) Morgan associated with Quercus species in three sites of scarce precipitation in the Altiplano Potosino.Materials and methods: Ectomycorrhizal fungi and vegetative structures of oak were collected during the rainy season for morphological characterization and identification. Soil physicochemical variables were evaluated by Tukey’s analysis of variance and least significant difference (P = 0.05), to identify differences among the studied sites (Cerro El Peñon Blanco, Sierras de Guanamé and La Mojonera).Results and discussion: The ectomycorrhizal species A. aff. hygrometricus was associated with Quercus potosina Trel., Q. pringlei Seemen ex Loes., Q. tinkhamii C. H. Muller and Q. striatula Trel. The fungi had five to 14 laciniae per basidiomata and the following diameter ranges: 13 to 20 mm (endoperidium), 42.3 to 57.4 mm (exoperidium), 8 to 10.1 µm (spore length), 4.4 to 6.9 µm (endoperidium hyphae) and 4.9 to 9.2 µm (exoperidium hyphae). Oak and fungal species were found in friable soils (sandy to clayey) with pH 5 to 7.7 and low nitrogen (<2 %) and high phosphorus contents (85 mg∙kg-1).Conclusion: The ectomycorrhizal association of A. aff. hygrometricus with oak species explains the survival of these shrub oak forests under the semi-arid environments of the studied sites.

Introducción: En las partes altas de sierras del Altiplano Potosino existen bosques relicto de Quercus spp. Hasta ahora se desconocen las especies de hongos ectomicorrícicos asociados a dichos ecosistemas.Objetivo: Conocer la morfología de Astraeus aff. hygrometricus (Pers.) Morgan asociado a especies de Quercus en tres sitios de precipitación escasa del Altiplano Potosino.Materiales y métodos: En la temporada de lluvia se recolectaron hongos ectomicorrícicos y estructuras vegetativas de encino para su caracterización morfológica e identificación. Las variables fisicoquímicas del suelo se examinaron mediante análisis de varianza y diferencia mínima significativa de Tukey (P = 0.05), para identificar diferencias entre los sitios estudiados (cerro El Peñon Blanco, sierras de Guanamé y La Mojonera).Resultados y discusión: La especie ectomicorrícica A. aff. hygrometricus se asoció con Quercus potosina Trel., Q. pringlei Seemen ex Loes., Q. tinkhamii C. H. Muller y Q. striatula Trel. El hongo tuvo de cinco a 14 lacinias por basidioma y los siguientes rangos de diámetro: 13 a 20 mm (endoperidio), 42.3 a 57.4 mm (exoperidio), 8 a 10.1 µm (longitud de esporas), 4.4 a 6.9 µm (hifas de endoperidio) y 4.9 a 9.2 µm (hifas de exoperidio). Las especies de encino y del hongo se encontraron en suelo de textura migajón (arenosa a arcillosa) con pH 5 a 7.7 y contenidos bajos de nitrógeno (<2 %) y altos de fósforo (85 mg∙kg-1).Conclusión: La asociación ectomicorrícica de A. aff. hygrometricus con las especies de encino contribuye a explicar la supervivencia de estos encinares arbustivos en los ambientes semiáridos de los sitios estudiados.
